How long will a battery backup sump pump run?
People also ask, how long will a 12v battery run a sump pump?
A 100 amp-hour AGM deep-cycle battery can continuously run a 600-watt sump pump motor for 1 hour and 20 minutes, an 800-watt sump pump for 1 hour, or a 1,000-watt sump pump for 45 minutes until fully discharged.
In this way, is a battery backup sump pump worth it?
Power outages can happen during strong storms, taking out the sump pump. If you have these situations a few times a year or even once a year, a battery backup will be worth the investment. This will eliminate the cost of repairs, water removal and other issues that come with flood damage.
Maintenance: It's pretty easy work, but having a sump pump battery backup, means one more thing to attend to. You'll have to add fluids to batteries that require it and replace sump pump batteries every 4-5 years.
